Abstract

We studied new structures of superconducting spin valves of Fe2/Nb/Fe1/CoOx and Fe2/Al2O3/Nb/Al2O3/Fe1/CoOx designs. The operation of these structures is built beyond the classical superconductor/ferromagnet proximity effect. The superconductor/ferromagnet interface in these structures is separated by an additional insulating layer. According to the results of our studies, the Fe2/Al2O3/Nb/Al2O3/Fe1/CoOx structures are the most promising structures for further research.
